What does a red light mean?

Answer: C — Stop and wait for the green light

A red light clearly signals that drivers must come to a complete stop at the designated stop line, intersection, or crosswalk and remain stopped until the light turns green. This rule is crucial for maintaining safety on the roads, as it helps prevent collisions and manages the flow of traffic at intersections. Understanding this fundamental traffic signal is essential for all drivers, as it ensures that all road users can anticipate each other's actions. The indications represented by other choices do not align with traffic laws regarding red lights. For instance, proceeding with caution or yielding to oncoming traffic could lead to dangerous situations if drivers misunderstand the directive to stop. Speeding up to clear an intersection when the light is red is also unsafe and could result in accidents. Hence, knowing that a red light means to stop and wait for the green light is vital for legal compliance and safety on the road.
